Question

Resolva com equação, U = Q: 2x + 10/4 – 3 (3 - x)/2 = 56 + x/2

Answer 1

Oie, Td Bom?!

2x + 10/4 - [3(3 - x)]/2 = 56 + x/2

2x + 10/4 - [9 - 3x]/2 = 56 + x/2

4(2x + 10/4 - [9 - 3x]/2) = 4(56 + x/2)

4 . 2x + 4 . 10/4 - 4 . [9 - 3x]/2 = 4 . 56 + 4 . x/2

8x + 10 - 2(9 - 3x) = 224 + 2x

8x + 10 - 18 + 6x = 224 + 2x

14x - 8 = 224 + 2x

14x - 2x = 224 + 8

12x = 232

x = 232/12 ⇒ x = [232 ÷ 4]/[12 ÷ 4]

x = 58/3
